In the broadest sense, I am interested in theoretical and applied questions about the evolution and ecology of amphibian species and communities. For the past 6 years my research program centred on population genetics in human dominated landscapes, focussing on gene flow interruption and its consequences for amphibian populations. Part of this research also investigated the fitness consequences of phenotypic and genetic variation. Amphibian populations are facing various threats in Northern Ontario such as habitat removal, connectivity disruption and EIDs and my research ultimately integrate all these aspects to understand the declines of populations.

In general, my work integrates intense field work coupled with molecular approaches for the analysis of parentage and population genetics, and laboratory experiment to estimate measures of fitness.

Currently, I work as a research scientist with Environment and Climate Change Canada.
